摘要 偶氮染料废水是一种有机物含量高、成分复杂、色度高、可生化性差的难降解废水,其处理方法已引起广泛关注。用Fenton氧化法研究了五种偶氮染料(橙黄Ⅱ、橙黄Ⅳ、铬黑T、皂黄和酸性铬兰K)的降解脱色情况。研究结果表明,这几种偶氮染料均有显著的降解。当偶氮染料浓度为200ppm、H2O2(30%)的用量为0.2ml、Fe SO4·7H2O用量为83.4mg,反应1小时后,橙黄Ⅱ和铬黑T在p H=10时的脱色降解率高达94.55%和88.19%;橙黄Ⅳ和酸性铬兰K在p H=12时降解脱色率是最高的,达到了98.74%和96.97%;而皂黄则在p H=2时的降解脱色率最好,高达97.36%,是一个降解高浓度染料废水的有效方法。根据偶氮染料降解后的UV-Vis图谱,简单探讨了氧化过程中可能的反应机理。 Azo dye wastewater is hard to degrade due to its high content of organic compounds, its complexity of the components and high chroma. And its treatment method has been concerned extensively. The oxidation degradation of five azo dyes (orange Ⅱ, orange Ⅳ, eriochrome black T, soap yellow, acid chrome blue K) was studied by Fenton reagent technique. The study results indicated that when the concentration of dye was 200ppm, the dosage of H2O2 (30%) was 0.2ml, the dosage of FeSO4 ·7H2O was 83.4mg, the reaction time was lh, the decolorization rate of orange Ⅱ and eriochrome black T was 94.55% and 88.19% (pH=10), respectively. The decolorization rate of orange Ⅳ and acid chrome blue K was 98.74% and 96.97% (pH=12), respectively. The decolorization rate of soap yellow was 97.36% (pH=2). Based on the UV-Vis spectra of zao dyes after degradated, the possible degradation mechanism was discussed simply.
